Water surface object recognition system and method and application based on 5G MEC

Abstract

The invention discloses a water surface object recognition system and method and application based on 5G MEC. The method comprises the steps of completing a water surface object automatic detection and recognition model based on an improved Yolov4 deep learning method through an edge cloud in advance, temporarily storing model parameters, and making a new image sample through the returned data, so as to update the model, and achieve transfer learning; and finally, sending an identification result to an unmanned ship control system and a user side. The system comprises an unmanned ship and an edge cloud module. In the application of water surface object recognition based on 5G MEC, video data are converted into video code stream data, the video code stream data are uploaded to edge cloud by adopting a 5G network communication module, and the edge cloud is used for detecting and recognizing a water surface moving target. According to the scheme, YOLOv4 is combined to serve as a target detection algorithm, the optimal balance between the detection precision and efficiency is achieved, the depth and transfer learning recognition algorithm is combined, the obstacle avoidance capacity of the unmanned ship is enhanced, and the garbage collection efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent recognition, in particular to a system and method for water surface object recognition and an application based on 5G MEC. Background technique [0002] At present, there are many kinds of garbage on the surface of the water. In order to improve the functionality and safety of the clean unmanned ship, the unmanned ship needs to judge whether it is garbage collection or obstacle avoidance when sailing, and the existing unmanned ship lacks a surface object recognition system; existing The ground station of the clean unmanned ship lacks a high-definition video return system and a visualization platform, and cannot provide real-time and intuitive feedback of surrounding environment information to users, resulting in poor user experience in deployment configuration. Therefore, how to quickly realize water surface object recognition and intuitive feedback It is very necessary for users; [...
